i( Application led October 10, 1927.' Serial No. 225,267.

This invention relates to fastener-inserting' machines and is herein :illustrated as em- Y materialhas been presented in an unperfobodied in a. machine for inserting lacinghooks in articles ofwork, for example shoe uppers. v Y l Because of the strains to which lacinghooks are subjected by the lacings, it is customary, in manufacturing, shoes,'to reinforce the uppers Aat thefhoolr-receiving.portions with pieces of non-elastic, woven fabric laid against the inner surface of the upper leather,

and to clench the barrels of the hooks upony these reinforcing elements.

portions of the-hooks and the reinforcing piecesare subsequently covered by Stitching inner facing strips to the upper. Former developments in this branch of the art provide means for automatically presenting a `strip of reinforcing material to the hook-inserting mechanism of machines of the type mentioned, and means for severii'igthe strip into yindividual sections, usually about onehalf inch Square, so that each hook will be providedwith one of them. In all such machines heretofore provided the reinforcing rated condition to a combined. punch and .clenchinof tool of vthe hook-inserting mechanism, to be punched by said tool as the latter punches holes in the upper for the reception of the lacing-hooks. Nevertheless, certain objections arisefrom using such a punch to punch holesin the .woven fabric provided for reinforcement. A Since thepunching portion of a combinedpunch and clenchi'ng tool must be small enough to enter the smaller end of i the barrel-portion of the hook, theholes punched by such a tool for the reception lof 'the hooks are considerably smaller thanv the clenched portion of the barrel and this in' turn causes so much `protriision of the clenched portion that the lump formed by the latter can be felt through'the inner facing by the wearer of the shoe.

Again, when the reinforcing fabric is `.punched as formerly while it liestupon the The clenched upper leather, the hole-punched inthe reinforcing fabric is not clean-cut. in part to the resilience ofthe leatherbacking and in part to the fact that the punch,

. by reason of theother functions it has to perform, does not have a sharp cutting edge, since a sharp cutting edge would be dulled, if not broken, by the pressure With which it is forceda-gainst. the punch-be In View of the conditions described above, an object of the present invention is to pro- This is (due vide, in a fastener-inserting machine of the f type mentioned,.improved means for -punching fastener-receiving holes in the material used to reinforce the anchorage of the inserted fasteners. Another object closelyirelated thereto is to provide means .for punching holes in the reinforcing material larger than `the holes punched in the upper, to the end that theholesjpunched in the reinforcing material may be as large as the outer diameters of the shanks of the hooks, or, if preferred,

o f any other desiredsize irrespective of the size of the holes punched in the material `to be reinforced. V

'Accoidinglyg a feature of the invention consists in means arranged to punch-fastener-receiving holes successively and exclusively in a strip of reinforcing material, and

means arranged to feed thestrip tov place said holes successively in` register with the-punch. lof the fastener-inserting mechanism. In the illustrated machine the said means for punching the reinforcing material comprises a punch-and-die couplewhich operateswith a shearing action and which Vis adapted to effect a clean cut, Vsince the fact that the vdie member is formedwith a hole to receive the punch provides for the use of Sharp shearingedges on' both members.

Inmachines of the type referredy to, itis customary to provide means for automatically severing the reinforcing material into `individual sections, Ypartly to avoid wasting reinforcing iiiaterialand partly to preserve in the highest degree the flexibility of the upper. Accordingly', the machine illustrated herein is also provided with strip-severing means arranged to sever a section of the strip of the fastener-insertii1g fmechanism.v As herein shown,` and in accordance with another feature of the invention, the punch for operating,r Aon the reinforcing strip individ.

that has been'fed into register with the punch the sections of reinforcin lone) length irrespective of' lacing-hooks. "Accordingly, another uully, the punch for perforating the upper, and the cutter for severing the reinforcing strip, are all carried and actuated by one plunger.

, ln accordancewith custom, the illustratedV machine is provided also with Workffeeding mechanism capable of being regulated to vary the spacing of the lacing-hooks, as' may be required by shoes of various sizes or by the number of lacing-hooks to be inserted in each shoe. Nevertheless, the sections of reinforcing material need not be, any longer when the [lacing-hooks are spaced relatively far apart than -ivhen theyl are nrelatively close to 'Teach other, and in the interest of economy of reinforcing material it is desirable to sever fr materia-l all to llie spacing)` of the odiject of the invention isto provide in'iproved means l formeasuring the sections of reinforcing material all to one length,` Whether the feeding 'means be regulatedto effect relatively long i, feeding steps of they upper or relativelyr short "feeding steps. .Tothis end a featurel of the invention consists in strip-feeding means operated by the upper-feeding means .to feed the stripforyvard 'with the 'saiiie amplitude of movement as that imparted to the upper, and regni-table means for causing the strip-iceding means to feed the'strip `iii the opposite directioin,l after each forward step, a relatively short distance equal in every case to Lthe'A difference betivcen the length of the forward step and the desired lengthof the individual sections. Thus, While both theforward steps andthe relatively short reverse steps imparted to thcstrip are varied by y regulations of the upper-feeding means, they are varied equally, with the result that the net feed of the strip is always constant 'and iisures a constantlength of the individual Sections.

The operator of a machine for inserting lacing-hooks usuali i sit-sat the machine and e. D y places-fa stock of shoe uppers in his lap, and

as cach piece of Work is finished he lays it aside and picksup another yfrom the stack in his lap and places it on the Work support of the machine. In machines of this type the lacing-hook-inserting means comprises a horizontal plate to which each lacing-hook chlivered from a vraceivay and hy which the li'ookis raised and insertedinto the work.

`Following the insertion ofr each hook this plate, which is at they front of the machine, must beretracted from the throat of the `clenched hookby movement toivard the op- Herator, and the mechanism for so moving the yplate is customarily located infront of the hook-inserting plunger and therefore adjacent-t0 the )ath "of travel of `the'uppers as they are raised rfrnitheoperators lap to ItheWorkfsuppornV "In `prior machine'sftliis mechanism for retraeting the plate has projccted so far towardthe operator :is to overhang the stack of uppers lying in his lap, and has retarded productioirby interfering with thelifting of the uppers from the stack to the work-plate. ^In view of this condition, a still further object of they invention is to do away with the objectionable overhang of the iuech- 'anism for ret 'ac-.ting the hook-supporting plate, so that said mechanism will not prevent lifting the uppers from the stack in the most convenient and most direct path..

Accordingly, in the illustrated machine, the

motion for rctracting the hook-supporting i plate is communicated thereto from a` cani by a single element, namely, a lever carried up and down relatively to said cam by said plunger and arranged to engage both the cani and the plate. .This form of iiiechauisin not only eliminates the aforesaid overhang, but also provides for maintaining the lever iii operative engagement ivith both the hooksupporting plate and the cam without articulating the lever.

The invention also provides other improvcments which are hereinafter described andA claimed and illustrated in the drawings.

Referring toFigq-l, the frame 15 ot the machine is provided with bearings for a horizontal cam shaft 16 equipped'ivi'th Vclutch mechanism including` a continuously :driven pulley 17. This shaft carries a`ca1n. 18 for operating the combined punch and clenchin'gi tool, hereinafter described, a cani 19 for operating regulatable 1 Work-feeding mecha- Vnism, a cam 2()l for operating mechanism by Which thelacing-hooks in the raceivay-are "separated and delivered to the hook-inserting mechanism, a. cani 21` for lifting the .pressei'f00t 115,` acam 22 (Fig. 2) tor operating the hooleinserting plunger-23, and a thin face-cam 24 fori'etractiiig the hooksupporting plate-29 from the throato'f the clenched hook. y

The plunger 23is arranged to slideup and down in bearings formed in the frame 15y and is maintained in said bearingsby ak detachable cover plate in which the caui 24 is `nested `(see Fig. 1) and which 'has so little fblock .28` 1\'vhicli-carries a laterally-`movable liook`-supportingplate29. The stem'27 is retained in the plunger 23 by a scr'eiv Z50 and. is normally held vdown byV a. compression `spring 31. f Anut 32 screwed on -a threaded portion 33 ofthe stem 27 provides for ad` justing the block 28 up and down relatively to the plunger 23 `t0 regulate the"pressure with Which the lacing-hooks are inserted and clenched. The bloc'k28 is tormed'ivitli hoiizontal grooves 34. inl which opposite edgesoi the hook-supporting'plate 29 may slide. The

`mid-section of the block 28 is cutout to receive the upper end lof a lever arranged to shift the'plate 29 to the front and rear.

"This lever is carried up anddoivn by the plunger 23 and isv `connected thereto-hy a pivot pin 36. The upper end of the lever 35 isstraddled byz teeth37forined on the bottom of the plate 29 and is normally drawn to `the rear by the tension spring 38. -A roll 39 set into the lower Vend-of the lever l35 is engaged by the rearlface of the cani 24,` as shown inFig. 1. .The diameter of' theeam 24 is sufficient to maintain Contact ivith'theroll 39 notwithstandingthe factthat the lever 35fis carried up and down by the plunger 23,

but theup and1do`wn movement of the lever has no effect on theposition of the plate 29 relatively t0 theblock 28. The rear edge of receive the neck l1 (Figi 11) of a lacing-hook which is deposited. on the plate by mechanism I hereinafter described.`

Lacing-hooks are t'ed from a hopper l2 (F ig. '1) `to an inclined raeeiv'ay 43, portions of which are shown infFigsyB, 4f, 5, 6 andll.l

This racervay conductsla series ot lacinghooks to an-oscilatory separator ell affixed to 1a'pivot member 45. `The leadingvlacing- .hook of the series gravitates from the` race Way 43 to the separator 411 and is temporarily supported by the latter, but at a suitable time in the cyeleot operations the separator "is turned in a counter-clockwise direction Vto release said lacing-hook, whereupon thel latter slides down a supplemental raceivay Llli the delivery end of. which is horizontal'.` VYVlieii thev plunger 23' is in its louest position itliolds the plate 29 atthe level ot' the-de "livery end ot'ithe raceivayfl, and at this time `the rearedge of the plate 29 is maintained in contiguous relation to said raceivay by theV spring` 38.

Eachlacing-hook, after gravitatingto the delivery 'end of the raceivay 4G, is transferred from said raceivay tothe supportingplate'L .29*by `a pusher 17. i This pusher is carried by a horizontally movable'plunger t8 ar-` ranged to slide in abearing 49. The pusher is nested in theplunger 418 and is adapted 'to yield relatively thereto to guardagainstL .breasage in case the 'raceivay 46 is obstructed or the lacing-hook becomes wedged therein; A pin carried by the plunger 4S lextends through a recess 51 in the pusher Ll7tofpro vide a connection, and a compression spring 52 normally maintains the pusher iii an ad- :vanced position relatii'fely to the plunger. .The plunger is reciprocated to the front and rear by the Cain 2OV and a lever53 actuated thereby.` The lower end of this leveris finountedon a stationary pivot member `54;, "and the upper end is ormedivith a forked portion which straddlcs a stud 55 projecting `the plate 29isprovided`with a notch l0 to from a sleeve 56 looselysurrounding the rear 1 portion of theplunger 48. A compressed spring 57 surrounds the plungei.' 48' lbetiveeii the-sleeve 56 and acollar58` affixed to the plunger, thev spring being maintained un-V der compression by a collar 5.()A a'liixed to the rear end of the plunger. Thus, when the level' 53 moves the sleeve 56 toward theiront of the machine. its'inoveinent is transmitted to the plunger 48 by this spi'ing 57 unless some i obstruction:prevents such movement ot the plunger. in which case the moi/'ement of thel sleeve 56 Will be dissipated in `further come pression of the spring 57.

The movements ot the plunger 4S are utilized lalso to operate the hook separator fifi through `connections now to be described. A'

lug 60 formed on the collar 58 is arranged to engage a lever' 61 `loosely*mounted on the 'pivot .member 45.

F ig. llfby thespring 66 and thepin 65, yand the lever 61 is normally held in the position shown in said ligure by the spring andthe screw 62. l

The mechanism just described operates as follows: When the plunger 48-is moved to the right from the position shown in Fig. 11,

ity not only retracts the pusher 47 from the raceway 46 but it also .causes the lug 60 to turn the lever 61 and the separator 44 in a counter-clockwise direction against the tension of spring 66. Since the lower endof the lever 61 moves in an are while the lug 60 moves 1n a .straight line, these twoparts lose contact with each other before theplunger 48 reaches thev right-hand limit of its stroke. Consequently, the escape of the lever .61 from the lug permits thespring 66 to return the separator 44 immediately to its initial position, thereby giving the separator a considerable period of dwell in its hook-receiving position. lVhen the plunger 48 moves from right to left to transfer the separated lacinghook to the supporting plate 29, the lug 60 once more engages the lever 61 and turns the latter inl a clockwise direction against the tension of the spring 63. Here again, the arc of movement of the lower end fof the lever 61 permitsthe lug 60 to pass under and beyond it so that the lever may be returned to its initial-"position by contraction of the spring 63. When a lacing-hook is delivered to the plate 29, the head of the hook lies under said plate and the barrel projects upwardly therefrom, as illustrated in Fig.`4.

Referring to Fig. 10, the fastener-inserting mechanism also comprises a tool for cooperating with the hook-supporting plate 29 to clench the hooks. This tool comprises a clenching portion 67 and apunch or pilot 68. The diameter of the punching portion 68 is smaller than the internal diameter of the barrel portion X (Figs. 4 and 11) of a lacinghook but is suliicient for the purpose 'of punching holes in leather shoe uppers,since the leather will stretch readily to receive the lrarrel portions. `'l`hepunch68 cooperates lirst Vwith the work-support or punch-bed and moves laterally therefrom for the purpose of feeding the work step by step to space the lacing hooks one from another. As shown in Fig. 10. said tool is affixed tothe lowerend: of a plunger 69 and the latter is arranged to slide up and ,down in bearings 70 formed in a horizontally movable feed carriage'7 1. A cross-head `72 ailxed to the plunger 69 is providedwith a horizontal groove for the reception of a'crank block 73. This block is bored for the reception `of a crank or wrist pin 74 carried by a rock-shaft vis actuated to punch holes infan upper 8O (Fig. 12) for lacing-hooks.

The feed carriage 71 69 is carried from side to Side is connected to the frame 15 by two horizontal guide rods 80 and is reciprocated by a train of mechanism that receives motion from the cam 19 (Fig. 10). A connecting rod 81 is formed at its lower end with a guiding slot 82 through which the shaft -16 extends and is also provided with a cam roll 83 arranged in `tbe groove of the cam 19. The u per end of the rod 81 is provided with a forl o straddles an arm 84 of a bell-crank lever supported by and surrounding the rock-shaft 75. The arm 84 is formed with a slot 86 to receive an adjustable pivot connection 87 by which the rod 81 is operatively connected to the bellcrank lever. This lever includes ,also an arm 88 and a sleeve or hub portion 89 connecting the arms 84 and 88. The arm 88 is formed with a vertical groove for the reception of a block 9() lpivotally connected; to and carried by the feedcarriage7l. Theflength of motion imparted by this mechanism to the feed carriage may be regulated by shifting the pivot connection 87 toward and'from the axis about which the lever 84, 88, 89 oscillates, and to providefor such shifting the upper end of the connecting rod 81 is connected by a link 91 with a regulating lever 9 2. fThis lever is affixed to a rock-shaft 93 and is provided with a gear segment 94 engaged by a gear segment 95 formed on an adjusting handle 96. The handle is supported by a pivot member 97 and is maintained invarious positions of adjustment by a spring-pressed,retaining tooth 98 which plays over a stationary toothed segment 99.

The parts hereinbefore describedoperate in well-known manner'to punch holes in an upper for the reception of the shanksof lacing-hooks, to feed the upper step by step and to insert and clench the lacing-hooks. In addition thereto and in accordance with a novel ,feature of the 4prese-nt invention, the machine is provided with a supplemental punch 100 (Fig. 8) arranged to punch holes in a strip 103 of reinforcing material automatically Supplied Afor .the purpese 0f reinthe reception of the barrelsof by which the plunger ed head which 'l lll forcing the anchorae of the lacing-hooks(V The punch -100 is pre erably larger in diame- `ter than the punch 68 and-iscarried by a block 101 ailxed to the plunger 69 (Fig. 4). y The block 101 also carries a cuttei 102erelastic. It is commonly impregnated with a Y paste by which itfis rendered moderately stiff so that it zwilli not. wrinkle or bend too easily. As the strip 103 leaves the receptacle 105, it passes. through a guide 107 and is drawn downwardly through va `guide 108.

.From` tlielatter it is drawn along a curved,

segmental guide 109 having an e e 110 at its lowerendand also-having a leaf spring 111 which cooperateswith the eye 110 to ,maintain alight clampingpressure on the strip. Froin the eye 110, which is slightly above the levelfof the work support and punch-bed 112,the`st'rip103 passes througha guiding channel 113 (Fig.(9) in a sectional block 114.

r release the upper 80 periodically, .but inaddition to being moved up and `down bythe The bottom section of this block provides a punchbed with whichl the punch 100 cooperates topunch fastener-receiviiig holes in the strip103, but :preferably a hole 11.7 ex tends through the block and intersects the channel `113 to receive thevpunch 100. Thus, as shown in Fig.. V8, these elements provide a punch-and-die, couplel Q adapted Y to punclii clean-cut holes :in the,reinforcii`ig material. independentlyl ofthe ,work 80. Figs. 7 and 8V show the punches having just completed a punching operation... y

The block 114jis ysupportedby ajfpresser foot "115 which cooperates in well-known manner with the `punch-bed 112 to clamp and presser-foot the blockf114 is `connected f with vthefeed carriage 71 Sothat-it Vpartakes also of? the horizontal reciprocations ofsaid carriage for the purpose of feeding the strip 103. The block 114 is-tlierefore formed with a dovetail portion 116V which slides in a groove of corresponding shape formed in the presser-foot.- The connection by which the `block 114 is caused to `move back. and;

. forth with the carriage 71 maintains not only the ,cooperative relation, of the piinclranddie ,couple but also maintains the left-hand. end of the block infcontact `with the cutter 102; Thus, the'cutter102'andV block 114 constitute a shearing couple by which the in,- dividual sections 104 are severed with a clean The block 114 is maintained in cooperativeV relation to the punch and the cutter 102 by a collar 118 fastened to the'ffeed `carriage 71 andby alhollow,verticalfpin 119 (Fig.

5). This pin is not affixed tothe collar 1.18 but is adapted toslidey vertically.therein` as i required by the up and down movements of the presser-foot.` The pin also yextends throughand slides in a bearing in `the block 101 and its lower end` projects intoacavity i 120 in the block 114. A compression spring 121 seated `against the pin 119 and against a wall of the cavity 120 maintains pressure ofv the block 114 againstA the severing cutter 102, and a screw 122 screwed into the block 114 enters a cavity in thepinl119 to maintain f *y connection of said pinwith said block. A i

compression spring 123 is seated against an under surface ofthe feed carriage 71 vand maintains Adou/nwardV pressure on the pin..

119. This spring loosely surrounds a1 sup- 7 pleniental guiding pin 124 "which lis affixed` to the carriage 71 and is arranged `intelescopicrelation to the lhollow pin V119. -A Supplemental compression spring. 1251 is f seated against the lower end of the pin 124 and maintains additional downward pres-4 sure on' the hollow pin 119.

)Vhen the parts occupy their initial posi, tions, as shown in Figs. 2, 3 and 4, the punch'-` ing plunger 09 is raised, the presser-foot 115.

isdepressed by aheavyspring 140 (Figs.1

This accounts for th'e slack condition of the'striplO, as sh'pivn in Figs. 4 and 5, between the tension' device 111 and the blo'ck 114. s

Thcoperation of the'spur 126 is asv follows: Assuming the parts to be in their initial posi tions, as shown by Fig. 4, andwthat the feed carriage 71 moves from right toleft in con formitv with the cycle of operations hereinl before'described, the leading end of the strip' 108 will move with, and to the saine extent as;`

the carriage 71. Wien this' movement'of the carriage begins, the presser-foots raised and the spur 126 is depressed so that it maintains a' grip upon the strip in' addition to the hold which the punch y has on the` strip. Be` vfore the feed carriage 71re`aches the leftliaiid limit of its feeding stroke the spur 126i is released by the plate 131,andat the point where this release occurs the spur is retracted from the strip 103 bythecoin'pression spring 128. Nevertheless, the strip" remains" inter` locked with the sliding block"1l4 since it is still iinpaled bythe punchlO.' 1 When, after the feeding stroke has been' `completed and the v lacing-hook has been inserted and clenched,` the presser-foot descends andthe plunger 69 retractsboth the p'unch "68 andfthe punch" 100, the reinforcing stri'pi-is 'momentarilyref leased from all connection with the feedinlg means, although it s'ti'll entends loose 'y through the channel 113 4in'th'efblock 114.4t

Noxv, as the feed carriage 71 lmoves frdin left to right in returning tol its initial position, its

first stagesjof such movementproducenoV4 change in the position of the strip103; Since the latter is clamped by the tension elements" 110 and 111 and the stripjhas sufficient stiff ness tovrewsist Whatever slight friction' is. ex# erted upon it bythe block 114 thrugh which it entends.' Indue course; however, the head of Ithe spur 126 again encountersl the stri` tionary 'Cain surface 130 and'is'tliereby de pressed to foi'ce the pointedend of the spur into the strip, the block 11,4 continuing toy rnove to the right' to a greateifor .less exteht, aceording to thelengthl of feeding motion for which kthe regulatable :work-feeding imecha` nisni is adjusted. It is to `be understood that hij lio

becauseV adjustments of the Work-feeding mechanism do not affect the left-hand limitiofmovement movement to the right will be increased or decreasedrby regulation ofthe Work-feeding,r mechanism. Consequently, `the leading end of the strip `will project in every ease. thel same distance beyond the left-hand end of the sliding block 114 when the spur 126 is depressed by the cam 130, and anylsubsequent movement of the. block to the left orrightl v`will, cause theleadingjend of ,the (strip to move with it. That portion of the strip that lies between the sliding block `and the tension'V members and 111 yvill'therefore be buckled moreor less as shownin Figs. 4 and 5. The slots 133 formedin the cam plate 131 provide for adjusting saidplate so that the spur 126 will gripthe strip 103 at the instant when the previously punched hole in thefleading end lof the strip is in register With the U Y msm for feeding an article of worlr to space punch 68. s i

i If itis desired to` applya reinforcing stripv Without severing it into individual sections,

that result may be obtained by substituting a'v shorter cutter for the` cutter 102 and detachingthe cam plate 131 from the pressure-foot. Then, when the presser-,foot is lifted by its cam 21 it Will'punch a holein the strip 103 as.

already described, but will not raise the strip far enough to sever` it.V Moreover, the `spurl will remain outof contact with the strip i and the latter VWill `be fed with the same i amplitude as the, article of Work80. ith

` disconnecting; the,` driving y l manual operation of the presser-footmaybe,`

effected by a treadle not shown) and connections Whiclnas, shown in Figs. 1 land2, comthel shorter cutter the; stripmay be severed byinanually lifting the pressure-footbetiveen thelast andthesecond last cyclesof a series,

at which timeithe automatic operation ofthe machine Willbe momentarily interrupted by clutch. 4 Such prise a treadle rodwlfll, a lever 1fl2a-nd` the presserfoot stem143. The lever 142 affords a greater;l1ft than the cam 21 to accomplish this result. Following such manualsevering,

one` more cycle of fthe machine Will insert `a fastener 1n the one remaining hole previously punched inthe severedand partially attached portionof the strip.y n

Referring to Fig. 9,1the presser-foot 115-is formed with a recess 135 to clear the edge gage 136 shown in Fig. 3, and at the same y time to provide the presser-foot with two spaced Work-engaging portions 137and 138. Thus, While the edge `gage is aiiixed tothe Work i support `1'12it is "also nest-ed, in the,`

presser-foot between the portions 137 and138.

The portion 137`is arranged to'clamp the workbehindland in 'line Withthe fastener= insertinglocality while the edge gage` 'is ar-A ranged to engage the work behind and in line 'Y Y with the punching locality. These tivo workengaging portions of the presser-foot, located respectively at the leftand right of the edge gage, guard against accidental skewing of the work and insure punchingthe holes Vin the upper and inserting the fasteners Vat points uniformly distantfrom that edge of.

the upper which isheld against the ed ge gage. l\,/[oreover,:since the clamping portion 137 co operates with a portion 139y of the ivoilrsupport directly behind the hook-,inserting lo. cality it guards against skeiving that might otherwise resultV from retracting the hoolrsupporting plate 29 from the clenched hook, particularly when a chip, a thick deposit of enamel on the hook, or aV malformation of the hook, causesa tight fit of throat ofthe hook.
